Yikes!! Not good...definitely not the norm as my 2012 has no hesitation in 1st gear in manual, S or S+ modes.

It is not turbo lag
in C there is a definite lag looking at the tachometer as pedal is depressed. Does not budge for a perceptible period of time which has absolutely nothing to do with turbo. I have not noticed in S or S+ or M but will check it over the coming weeks weather and time permitting. I do not notice and improvement when resetting adaptive tranny. The tranny reset did resolve the stutter step.

It could be the adaptive tranny is getting better at recognizing my style as I'm not noticing this as much as I used to. Sport mode helps a bit too.
I guess I have gotten used to it. You have to anticipate the delay and get off the brake earlier, allow the MCT to work the clutch into first gear and then you can go for it.
It was definitely a bit of a let down and adjustment when I first got the car. My C63 just went.

Yes if it was turbo lag the car would still move but be down on power until turbos spooled up. The issue is a stop and trying to pull out the cars have a big hesitation before anything happens. Defn not a lag issue . Its tranny or servo throttle issue. My 14 though is a lot better then my 12 was.
Now I tap the gas just a hair before and it has no issue.
You can fake out our tranny's very easily. If you want to be in a lower gear while driving rather then waiting for the normal downshift. Try blipping the throttle really fast . It will down shift without the car accelerating and will hold the lower gear for some time. Ready to take advantage of the power curve without wasting time on the downshift.

The 2014 e550 just moves when you tap the gas... No hesitation

I have the same problem, RennTech doesn't help and also have the PedalBox installed, that doesn't do a justice either...i'm puzzled.
It doesn't happen all the time that whats gets me, its inconsistent, hope that MB can come up with a solution.

I've noticed this lag on occasion as well. We'll see what they say when I bring it in for the 1,875 LSD fluid change.

The E550 has the 7 Gtronic transmission with a torque converter.
The E63 has the MCTwhich has a wet clutch.
You can feel the clutch slipping when you first start moving.
I am pretty confident that the owners that are complaining about lag and sluggish throttle response are treating the car like any other automatic where you don't have to worry about getting it in gear first.
With this car, or any MCT benz, you need to allow it to slip into gear before you give it a lot of gas. If you mash the pedal quickly before first has engaged the ECU will slow things down while it engages the clutch and then lets all the power go.
Try and think of it the same way you would think of a stick shift. You would get in gear before you gave it a lot of gas. Same thing here.
Again if you look for it you can feel the car slip the clutch into first gear... then you can wait for that sensation and the take-up before giving it a lot of gas.

E550 has a 7g transmission vs the MTC in the E63 (and 2012+C63).
My E550 has considerable lag compared to my C63, especially stopped/nearly stopped. I attribute this to the transmission and it's terrible (luxury) programming - even in sport mode it starts in 2nd from a dead stop (unless you floor it or paddle shift down), then it shifts way to soon (car likes to be 1000-1400 RPM) so the turbo's aren't kept spooled. Lag in the C63 is waiting for the spinning tires to hook-up with the road.
Expanding on Cocofishez - in my C63 when stopped if I stab the throttle to the floor it doesn't go as fast as if I roll on it.

The 2014 e550... The sport mode forces 1st gear start and I programmed the tcu to be aggressive and it stayed that way ... Hit the gas and go

You have 4matic right? I test drove a couple of E550 sedans that had 4matic before ordering my RWD coupe. Talk about contrasts in performance from a dead stop. I found the 4matic sedans felt a bit sluggish when going from a dead stop on a highway on-ramp to getting up to traffic speed. If you're not an aggressive driver, you probably wouldn't notice the slight lag. Stomping on the accelerator didn't seem to noticeably improve things. Maybe I'm wrong but I attributed the slight delay to how the 4matic system has to function in order to supply power to all four wheels and how MB would have probably programmed the transmission mapping to be more "conservative" to smooth out the ride for the average driver.
